To (ti/6 who/rt 1123 may concern:

Be it known that I, SAMUELA. M ENGZER, a citizen of the United States,residing at (Jollinsville, in the county of Grayson and State of Texas,have invented a new and useful Acety lene-Gas Generator, of which thefollowing is a specification.

This invention relates to acetylene-gas generators, and has for itsprincipal object to provide a gas-generator of simple construction inwhich provision is made for automatically controlling the feed of thecarbid to the tank by the movement of the bell of the gasometer, toprovide aself-closing valve for the carbidholder, to providefor theautomatic discharge of excess gas in case of overcharge of thegasometer, and to insure the opening of the upper portion of thegenerating-tank and the discharge of gas therein through the exhaust orescape pipe when the slush-valve is open.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and particularly pointed out in the appendedclaim, it being understood that various changes in the form,proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the accompanying drawings, Figure 1 is a perspective view of anacetylene-gas apparatus constructed in accordance with the invention.Fig. 2 is asectional elevation of the same.

Similar numerals of reference are employed to indicate correspondingparts throughout both figures of the drawings.

The generating-tank 10 is preferably cylindrical in form and hasaconical top 11, at the upper end of which is a carbid-holder 12.,having a sloping bottom which communicates with the upper portion of thecarbid chamber through a contracted throat 13, and this throat isprovided withavalve-seat 14 for the reception of a self-closing valve15, that preferably is cylindrical in form and of sufficient weight tomove to closed position by gravity. The valve is guided by a cylindricalcasing 17, the upper end of which is closed to prevent contact of thecarbid with the top of the valve, and said casing is held by Wings orribs 18, extending inward from the main casing.

Arranged in the generating-tank is a pair of cross-bars 19 and 20,forming guides for a valve-operating rod 21, which normally is out ofcontact with the valve 15. The lower cross-bar is provided with abracket .22, to which is pivoted a lever 23, having one end connected tothe valve-operating rod and the other to a rod 2 L, that extends througha tube to a point above the top of the chamher, said tube forming awater seal to prevent the escape of gas. At the upper end of the rod 2ais a guide 27, carrying a roller 28 for the support of a lever 29, andone end of the lever is pivotally connected to a bracket 30, extendingfrom the generating-tank, while the opposite end is connected by a chainor cord 32 to the bell of the gasometer, so that as the latter falls theweight imposed on the lever 29 will move the rod 2 L downward and effectu pward movement of the rod 21 and the opening of the valve, a quantityof carbid falling from the holder into the generatingtank. When thegasometer is filled, the valve iscallowed to close by gravity and thefeed is cut off.

At a point adjacent to the generating-tank is a gasometer 33, having amovable bell 34:, and the lower portion of the gasometer-tank is dividedby a partition 35 to form a lower washing-chamber 36, into which the gaspasses through a pipe 37. The discharge end of the pipe 37 below thelevel of the water of the tank 36, so that the gas is compelled to passthrough the water for the removal of impuri ties, after which it flowsthrough a pipe 38 to a point above the water-lcvel in the gasometer.

Leading from the gasometer is a dischargepipe 39 in communication with aservice-pipe 40, a suitable filter ll being interposed between the two,and below the filter is a dripchamber 4E3,into which excess water mayflow.

At the central portion of the gasometer is a vertically-disposedescape-pipe45, the upper end of which is considerably above the level ofwater in the gasometer, and surrounding this tube is a tube 46, carriedby the bell and having an open lower end that carries a suitable Weight47, this weight, added to that of the bell, determining the pressure ofgas in the service-pipe. The pipe acts as a guide for the bell, and itslower end communicates with a discharge-pipe 48, leading to any suitablepoint and preferably some distance from the generator, and said pipe isconnected to the main gas-pipe 37 by a branch pipe 4:9, having asuitable valve 50, which when open Will permit the direct flow of gasfrom the generating-tank through pipe 37 to the exhaust or escape pipe48.

At one side of the tank is arranged a pipe 52, that extends up above thelevel of water in the generating-tank and may be used to supply Water tothe latter, and at the lower end of this pipe is a gate 54:, which maybe opened to permit the discharge of the water and slush from thegenerating-tank. This gate 54 is connected to the valve by means of arod 55, and both are normally in closed position during the manufactureof gas. hen the gate 54: is to be opened for the purpose of cleaning thegenerating tank, the valve 50 is also opened, so that any gas in theupper portion of the generating-tank may escape to the outer air.

At one side of the generating-tank is a tube 57, its lower open endbeing adjacent to the bottom of the generating-tank, and through thistube extends a slush-bar 58, having a handle portion 59 arranged outsidethe reservoir for agitating the slush while the reservoir is beingcleaned.

In operation gas formed in the generatingtank will flow through the pipe37 to washer 36, and thence pass by pipe 38 into the gasvalve. The gaspasses out through the pipe 39 to the service-pipe 40, being purifiedduring its passage through the filter 41. hen the supply of gas in thebell is reduced, the lever 29 is pulled down, and this results indownward movement of the rod 24 and upward movement of thevalve-operating rod 21, said rod forcing the valve 15 from its seat andremoving the passage of a quantity of carbid from the holder of thegenerating-tank. The new gas will instantly How to the gasometer, and,the bell being raised, will again allow the valve 15 to move to its seatby gravity. Should the supply in the gasometer be excessive, the lowerend of the pipe a6 Will move above the water-line, and the gas is thenfree to flow through the tube 45 and escape-tube 48, passing to theouter air, and the discharging operation continues until the belldescends to an extent suflicient to again seal the bottom of the tube46.

When it is desired to clean the generatingtank, the gate 54 is opened,and its movement is transmitted through the rod 55 to the valve 50,opening the latter and permitting the escape of gas from the top of thegeneratingtank through pipe 37 and pipe 49 to the main escape-pipe 48.

Having thus described the invention, what is claimed is- In anacetylene-gas apparatus, a generatingtank, a carbid-chamber arrangedabove the tank, a self-closing valve controlling the flow of carbid fromthe chamber to the tank, a cylindrical valve-guide arranged Within thechamber and having a closed top for shielding the valve, supportingmeans projecting from the valve-guide to the wall of the carbid-chamber,a pair of cross-bars arranged within the tank, a valve-operating rodguided by said cross-bars and having its upper end connected to thevalve, a bracket carried by the lower cross-bar, a lever fulcrumed tosaid bracket and having one of its ends connected to the valve-operatingrod, a second rod connected to the opposite end of the lever andextending upward through the top of the tan k a sealingtube alsoextending through the top of the tank and surrounding and forming aguide for said rod, the upper end of said tube being funnel-shaped, aguide arranged at the upper portion of. said second rod, a rollercarried by said guide, a bracket rigidly secured to the upper portion ofsaid tank, a lever fulcrumed to the bracket and resting on said roller,and a gasometer including a movable bell connected to the opposite endof said lever.

In testimony that I claim the foregoing a my own I have hereto affixedmy signature in l the presence of two witnesses.
